The Hornets should have had a penalty in the 94th minute of the game. There is no questioning that fact.

Richarlison's ball hit Eric Dier's hand, which was not near his body or in a particularly natural position, and Martin Atkinson should have pointed to the spot.

That he did not is surprising, because he appeared to have a good view of the incident and the ball would have presented Andre Gray with a chance to give Watford the win.

Could Watford have had one earlier too? Richarlison was impeded by Ben Davies and knocked off his feet - Spurs scored from their subsequent counterattack.

It was less clear-cut, but it can be filed in the 'you've seen them given' category. Silva was certainly aggrieved.

But far earlier in the match, Spurs could feel hard done by. Harry Kane was preparing to slot the ball in from close range when Sebastian Prodl's sliding tackle appeared to deny him, without getting anyway near the ball.

He didn't complain, presumably because he was lying on the floor with a knock, Watford could not have had too many complaints if Atkinson had pointed to the spot, though.

Red Cards

It was of no real surprise that 22 players were not on the pitch when the game ended.

There was plenty of needle in the game and regular bookings too - the only surprise, perhaps, was that it was a Spurs player who went for an early bath.

Davinson Sanchez's elbow was naive and it happened right in front of the fourth official; there was only one outcome.

Whilst Spurs can have few complaints about that, they could rightly moan that Marvin Zeegelaar was still on the pitch come full-time.

He should have been booked for a cynical tackle on Dele Alli in the first-half, he was booked for a ridiculous off the ball tug on Alli early in the second-half and was incredibly lucky not to be booked for tripping Kieran Trippier.

Silva also had to take off Christian Kabasele and Tom Cleverley, with both on their final warnings after picking up early bookings.

Frustrating

Watford had 51 per cent of possession but could only muster two shots on target throughout the game.

The final ball was lacking - the same could be said of Spurs - and that was a source of frustration for Silva, who said as much after the game.

Whether it was when Doucoure, Tom Cleverley or Etienne Capoue trying to thread balls through for Deeney or Richarlison, or when Andre Carrillo, Kiko Femenia or Marvin Zeegelaar tried to cross balls into the box, it just did not come off for the Hornets.

Too often the ball was cut out by a Spurs defender, crosses were claimed by Hugo Lloris or they failed to find a yellow shirt.

That Lloris was not really forced into a save of not will disappoint Silva.

Whilst the fact that the closest they came was Doucoure's effort that hit the post from 20-yards out, which came as a result of a corner failing to beat the first man, says it all.

Kabasele's header was firm and his run well-timed, but the Hornets attacking play did not really warrant more than one goal.

Playing against ten men is not easy, Silva will want more though.

It was a solid Watford performance and everyone would have taken a point at kick-off - it was their first against Spurs since 2000 - but once again, there was a feeling that it could have been more at full-time.

Pereyra goes missing

This was a real opportunity for the Argentine to stake his claim for a run in the side, with Will Hughes likely to be absent for the foreseeable future.

Pereyra's Watford career is yet to hit the heights many expected, mainly due to injuries, so he'd have been keen to impress.

But Pereyra looked lost in the Hornets' 3-4-2-1 formation and struggled to get his foot on the ball and create opportunities.

Whereas Hughes has found pockets of space and seen plenty of the ball in this system, Pereyra did not.

Silva would have been looking at Pereyra, as well as Richarlison, to be their chief creators today, that did not come to fruition.

It was no surprise to see him taken off, although he may well have fared better when Kabasele was substituted and Watford reverted to four at the back.

He will be hoping he has another opportunity at Burnley, but there could be an argument that it will not be a game that suits his style.

Zeegelaar targeted.

Whilst Watford's defence was much better on the whole - Spurs' talented attacking line did not create many openings and Heurelho Gomes was left to claim crosses and mop up through balls - Zeegelaar struggled and, as has already been mentioned, was lucky not to see red.

Zeegelaar is an attack-minded wing-back and there was plenty of space in-behind him, which Trippier exploited willingly all afternoon, helped by some stunning passes from his team-mates.

The England international put in a number of dangerous crosses which caused issues for the rest of the back-line and could have resulted in goals.

Jose Holebas has found himself in that situation before and it is clearly an area opposition teams feel they can get at Watford from.

Whilst Zeegelaar has been excellent since coming into the side, this would have been a valuable learning curve for him and he'll now know, or be told by Silva, that he can't leave that much space behind him for the left-sided centre-back to cover.
